To all whom it may concern:

Be it known that I, OsoAR RoennrGnonxwrs'r, a subject of the King of Sweden, residing at Dayton, in the county of Montgomery and State of Ohiojg llave invented certain new and useful Improvements in Lubricating Systems and Controlling and Distributing Pumps Therefor, of-iwhich the following is a specification. f'

This invention relates to an improvement in lubricating systems for engines andlmore especially internal combustion engines and to apump 'for use in connection therewith.

One of the primary objects of the present invention is the provision of an improvedlubricatingsystem of this character of such:- a construction as to. insure just the proper amount of lubricant being delivered to the various points to be lubricated so as toob-[f viate the many objections due either to over-- lubrication or'to not enough lubrication.

Another object of the present invention is the provision of an' improvedsystem in which the lubricant will be supplied con: tinuously and under pressureto the various points to be lubricated.

A further object of the present invention is the provision of an improved lubricating system in which the various points .to be lubricated are arranged in groups, the- .points of each group being connected serially with a single outlet connection from the pump, thus insuring the delivery of a predetermined amount of oil to each point and also enabling a minimum number of oil delivery pipes to be utilized.

A further object of the present invention is the provision of a lubricating system in use in connection with a lubricating system which is designed to be positioned independently of the lubricant supply tank and is a small compact structure, so that when Specification of Letters Patent. Patented Aug. 14, 1917, Application fi1edAp1-i124, 1913. Serial No. 763,369. I

the system is used in connection with automobiles and the like, the pump may be pos1t1oned on the dash or at any other point where it will be readily accessible to the operator.

A further object of the invention is the acter which is automatic in its operation and is of such a construction that it will generate sufiicient pressure to force the oil through the outlet connections under all conditions, even if any of such connections become slightly clogged.

A further object of the present invention is the provision of a simple compact pump of this character comprising broadly a casicant and provided with a plurality of outlet connections, a rotary controlling and distributing member in 'said casing for controlling the admission of lubricant into the casing through the inlet connection and the discharge of the lubricant from the casing through the outlet connections, in combination with a displacement member which is automatically operable by the rotary controlling and distributing member and which serves to suck the oil into the casing and forcethe same out therefrom.-

Other objects of the invention will be apparent from the detail description hereinafter when read in connectionwith the ac companying drawings forming a part hereof wherein a convenient embodiment of the invention is illustrated, and wherein like characters of reference refer to similar parts in the several views.

. Referringnow more particularly tothe drawings,

Fig. 15 is a detail view showing. the means carried by one of the engine cranks which is utilized for transferring lubricant from the engine shaft bearing to the crank pin bear- 1n.

in the construction shown in the accompanying drawings, the system is illustrated in connection with an internal combustion engine. of the four cylinder type, although it will be obvious that it may be used with engines having any number of cylinders.

Referring now more particularly to the construction shown in the drawings, A designates the crank case of an internal com bustion engine, in which is journaled the engine shaft B and the cam shaft C, such shafts being connected by the usual timing which are housed within a timing gear casing l) which is conveniently formed as a part of the engine crank casing. In the embodiment of the invention illustrated, the

engine shaft is providedwith five bearings M E, F1, F3, FF, and F The'engme shaft isv also provided with four cranks F, each of which is adapted to be connected by a suitable pitrnan with a piston H which works within a cylinder H. For convenience of illustration, but one piston and cylinder are shown in the drawings, although it will be understood that the construction of the three other pistons and. cylinders is the same as the one illustrated.

'lhcportions of the engine shaft B which are positioned in the engine shaft bearings are each provided with suitable grooves therein enablin a lubricant to pass through the bearing and suitably lubricate the same.

the embodiment of the invention illusnest nae trated, that portion of the engine shaft groove 6' which is disposed upon the exteriorof the shaft, lubricant being fed under pressure,-in a manner to be hereinafter more particularly set forth to the bearing so that it-will enter one of said grooves and pass to the other of said grooves, thus thoroughly lubricating the bearing. Each of the two end shaft bearings is provided with means for transferring the lubricant which has been assed therethrough to one of the crank pin earings, such means comprising a dished ring I which is secured to one of the cranks adjacent the bearing and encircling said hearing, which ring is adapted to rotate with the crank and is disposed concentrically to the axis of the engine shaft. lhe

bearing is provided with a short tube 91 which communicates with the interior of the bearin and receives lubricant from one of the ho low grooves therein, the lower end of said tube being positioned to discharge into said hollow ring. The upper portion of the hollow ring I is provided with a port a i therein which communicates with a passage f which is drilled into one end of the crank pin and from the inner end of which extends a radially disposed port f, which port is adapted upon the rotation of the crank and the rotation of the pitman sleeve around the crank pin to be moved into and out of communication with a semi-circular groove '7 which is formed in the lower portion of the pitman sleeve. Means is provided for drawing oil into each of the crank pin bearings,

forcing the same therethrough and out I therefrom to the piston pin bearing, and from thence into the cylinder. in the particular embodiment of the invention illustrated, each of the crank pine is provided intermediate the ends thereof with an annular groove or channel 7 from which extend two diagonal grooves f and f, the former of which is adapted to be moved into and out of communication upon rotation of the engine shaft with the groove f in the pitrnan sleeve, and the latter of which communicates with a groove 7 which partially encircles the crank pin and is adapted upon rotation of the engine shaft to be moved into and out of communication with the lower end of. a pipe which is tapped into the upper portion of the pitman sleeve which surrounds the crank-pin, the upper end of said pipe projecting through the sleeve at the top of the pitman so as to supply lubricant to the bearing between said sleeve and the piston in l Secured in the lower portion of the sleeve of the pit man which encircles the'crank pin is a radially disposed sleeve F in which is loosely mounted so as to be freely movable, a plunger F which projects into the annular groove f which is formed in shoulder formed in the sleeve F, while outward movement of the plunger is limited by means ofan adjustable plug which is socured in the outer end of the sleeve F. By ad usting the plug the range of movementofv the plunger can be so varied that the dis-.

tance which the plunger moves out of the groove f 'can be regulated at will, so that the amount of oil which will be displaced at each inward movementof the plunger can I be regulated to suit the engine conditions.

Thepiston pin H is provided with suitable grooves into which the oil passes from the pipe 7 enabling the lubricant to be forced through the piston 'pin bearing and. .efiiciently lubricate the same and said piston pin and the pin are provided with .ports leading to the exterior of the piston, so that the lubricant will be forced after passing through the piston pin bearing into a groove h formed in the side. of the piston below the packmg-rings thereof from whence it will pass onto the wall ofthe cylinder. The particular construction of grooves in the piston pin forms no specific part of the present invention, but is covered in a separate ap-- plication, and hence'it is believed to be unnecessary herein.

The central bearing E of the engine shaft is provided with a pipe e leading therefrom, which pipe communicates with one of the annular grooves b of the po-rtionof the shaft in said bearing, the outer end of said pipe leading to one end of one of the end bearingsof the cam shaft C. Leading from the other end ofsaid camshaft bearing is a pipe 0 which communicates with one end of the intermediate bearing of the cam shaft C,and leading from the other end of the intermediate I bearing of the cam shaft C to one end of the other end bearing of the cam shaft is a pipe 0. It will thus be seen that any lubricant which is forced through the central bearing E will be also forced through all three bearings of the cam shaft G. Those portions of the cam shaft which are journaled within the bearings therefor are conveniently ro vided with grooves or channels to facihtate the lubrication of said bearings and the passage of the oil therethrough, the construction in the present case being the same as that heretofore described in connection with the engine shaft bearings. The pump which is used in connection with the present system is in the form of a small compact device, so

to describe the same in detail that the same can be, when the system is used-in connection with automobiles, readily secured to the automobile dash or at any other point where it will be easily accessible to the driver, and such pump comprises a cylindrical casing K, which in the present instance is illustrated as being fitted into the dash board of an automobile, the front of said casing bein closed and provided with a sight feed, is w ich may be of any suitable type. Closely fitting the interior of the cylindrical casing K is a cylinder K, which cylinder constitutes a lubricant controlling and distributin member, as will be hereinafter more partlcularly set forth, said member being adapted to be rotated through the medium of a-shaft K which is rigidly secured thereto and projects rearwardly therefrom, which shaft is adapted to be automaticall driven in any suitable manner from the engine shaft .sov as to effect the automatic distribution ofthe lubricant. In the present instance, I have shown'the shaft as providedwith a sprocket wheel K which may be driven in any suitable manner from the engine shaft. The shaft is also provided with a hand nut K so that the. oil controlling and distributing member may be rotated manually when the engine is not running,

should it be found desirable to do so. The rear'end of the casing K is closed by two superposed plates or members L and M which are rigidly secured in position in any suitable manner. The adjacent faces of the plate L and the rotary lubricant controlling and distributing member K are finished so as to obtain as near as possible a perfect contact with each other and the lubricant controlling and distributing member K is held up against the face ofthe plateL by means of a spring washer or other yieldable -means 70, which is interposed between the adjacent faces of the plate-M and a suitable abutment secured on the shaft K The form of the rotary distributing and controlling member is such that when the same is snugly held against thereof and the front wall of the casing,"

which space or pocket constitutes a lubricant receiving chamber. 7

In the embodiment of the invention illustrated in the. accompanying drawings, the plate M has tapped thereinto six outlet tubes N, N, N N N and N the outlet tube N leading to the bearing E of the engine shaft; the outlet tube N leading to the bearing E of the engine shaft; the outlet tube N leading to the engine shaft bearing E; the outlet tube N leading to the engine shaft bearing E the outlet tube N. leading to the engine shaft bearing E and the outlet tube N" leading into the timing gear casing D. As will be hereinafter pointed out, the construction is) such that lubricant is forced under pressure through outlet tubes N,'N, N N and N. The lubricant which passes from the tube N into the timing gear casing will not be under pressure, however, as before entering such tube the lubricant, as will be hereinafter more particularly set forth, passes through a sight feed, and consequently thereafter flows by gravity only. Tapped into the plate member M is also a lubricant inlet tube N which extends from any suitable lubricant tank 0 which may be positioned at any desired point. v Formed in the face of the plate or member M adjacent the member L are a plurality of grooves, the inner ends of which constitute ports whicharedisposed in a circular path around the shaft K There is provided one of such grooves for each of the outlet pipes and for the inlet pipe heretofore referred to; a groove n, the outer end of which communicates directly with the outlet port N; a groove n, the outer end of which communicates directly with the outlet pipe N; a'groove W, the outer end of which communicates directly with the outlet tube N"; a groove 12, theouter end of which communicates directly with the outlet pipe N a groove a the outer end of which communicates directly with the outlet pipe N a groove n, the outer end of which is connected by ports at and n formed in the body of the casing K with the upper end of the sight feed is, the lower end of said sight feed being connectedby a port if formed in the body of the casing with the outlet tube N and a groove n, theouter end of which is connected to the tube N which leads from the source of lubricant. The port at the inner end of the groove n communicates with a circular groove or channel P which is formed with projecting portions, the ends of which are fashioned to constitute ports 72 which are positioned in the same circular path as the ports at the inner ends of the grooves heretofore described which connect with the outlet tubes. The number, of

orts p employed corresponds to the number of outlet tubes which are used, there being in the present instance six of such ports. These ports are disposed intermediate the ports which are formed at the inner ends of the channels which connect with the outlet pipes. As the ports ya all communicate with a single annular groove or channel and as one of said ports communicates with the oil inlet pipe, it will be seen that all of said ports really constitute in effect a part of a single inlet port as when oil is fed to any one nfisaid ports, it will be fed toall of said ports. Formed in the plate Law a plurality of ports; Z which are disposed in a circular series aboutthe center of said memes 7 plate and which register with the ports 9 and the ends of the grooves n, 0%, n n n, n and u The ports in the plate thus constitute in reality a part of the ports heretofore described, but for the convenience of manufacture, the plates L and M are made separately. v

The rotary controlling and distributing member K is provided with a port or passage lc extending therethrough which, as the member K is rotated, is adapted to successively aline with each of the ports Z formed in the plate L so as to connect such ports with the oil receiving chamber at the front of the member K. The front surface of the member K is provided with a plurality of abutments projecting therefrom, 16*, which are disposed at equal distances around the outer ortion thereof, said abutments corresponding in number to. the number of outlet tubes which are to be utilized, there being in the present, case six subh abutments. In the particular embodiment of the invention illustrated, the abutments are provided with a flat upper surface and with an inclined portion leading thereto, al-

though the shape of the abutments may be varied. Tapped onto the front wall of the casing K of the pump opposite the outer portion of the rotary controlling and distributing member K is a sleeve Q in which is slidably mounted a plunger Q, the inner end of which is adapted to ride over the abutments k of the member K, when such member is rotated, and the outer end of which is provided with an enlarged head 9' which works in a hollow nut adjustably secured in the outer end of the sleeve Q. Interposed between the head 9 of the plunger Q and an adjustable stop g -which is secured in the end of the hollow nut is a spring 9 whichtends to move the plunger Q inwardly into the oil receiving recess or pocket which is formed between the front of the lubricant controlling and distributin member and the front wall of the casing The front wall of the casing is provided. with a suitable opening which is normally closed by a plug, which opening permits the pump and system to be filled with a lubricant before starting the same.

When the pump and system have been filled with lubricant and the lubricant controlling and distributing member K is rotated,either by reason of the rotation of the engine shaft or when the same is rotated manually, the port. 70 therein will be, as has heretofore been pointed out, caused to successively register with the ports [which are formed 1n the plate L and the plunger Q will be ments lo of the member K, and will thus be moved into and out of, either partially or wholly, the oil receiving pocket or recess,

caused to successively ride over the abut- P which is provided in the front of the pump casing. The construction is such that whenever the port 10 of the member K is moved into alinement with one of the ports L whlch communicates with one of the inlet ports 17, the plunger Q, will be just beginning to rest upon one of the abutments, so that as the port K passes over such port L, a quantity of lubricant will be drawn into the oil receiving pocket in the front of the casing equal in volume to the space displaced by the plunger as-it rides upon the abutment. As the plunger rides upon the abutment, the

port 70 of the member K will be moved out of alinement with the port Z which communicates with one of the inlet ports and into alinement with one of the ports. which communicates with one of the passages leading to one of the outlet tubes. As the port 70 moves into alinement with' this port, the plunger rides off of the abutment and is projected by its spring into the oil receiving pocket, thus forcing therefrom and out through said outlet tube a quantity of lubricant equal to the displacement of the plunger. This action will be repeated throughout the rotation of the member K, so that it will be seen that there will be constantly forced through each of the outlet pipes a predetermined amount of lubrlcant, which will be delivered to the various bear? ings in the manner heretofore described.

Owing to the fact that all of the outlet pipes except that which leads to the timing gears connect a plurality of bearings serially, it will be seen that each of said-bearings -is absolutely certain of. receiving its roper share" of lubricant, particularly in wow of the supplemental oilforcing means which is utilized .in connection with each of the outlet pipes. This serial lubricatlon of a plurality of bearings is advantageous not only because it reduces the number of outlet connections which are necessary, but also because where separate outlet pipes are led to the various bearings from a single oil supply, the tendency of thelubricant is to seek the easiest course, so that frequently some of the bearings do not receive any lubricant, while others of the bearings receive too much lubricant.

- By adjustably supporting the hollow nut Q in the sleeve Q it is possible by varyingthe position of the nut in said sleeve to vary the distance which the plunger will project into the oil receivingpocket and to thus regulate theamount of oil which will be drawn into said pocket and forced out therefrom through the various outlet connections, and as the sleeve and the hollow nut carried thereby are. mountedin-the front wall of the casing and are henceflreadily accesslble from the .drivers seat it will also be seen that any desired adjustment can be quickly plemental means automatically and readily made. To enable the operator to determine the extent of adjustment of the plunger obtained by shifting the nut Q the adjacent portions of said nut and the sleeve Q are conveniently provided with scale markings.

The advantages of a pump of the construction herein described are numerous. It 'may'be mentioned, however, that inasmuch as the pump is very small in size, it may be positioned at any place and at any distance from the oil storage tank, thus enabling the storage tank to be disposed in any convenient part of the machine, when the device is used in connection with automobiles. Furthermore, the construction of the pump is such that it will at all times automatically develop suflicient pressure to force the oil to the proper points under practically all engine conditions, even should the outlet pipe become clogged to a certain extent. The construction is also a highly advantageous one, inasmuchas the amount of lubricant which is forced to the bearings is automatically regulated so that there is nodanger of overlubrication or not enough lubrication, .and

invention is illustrated in the accompanying drawings, it will be understood that many changes may be made to the particular form and construction therein shown without departing from the spirit and scope of the invention as defined in the appended claims.
